Introduction

This plugin implements the wind simulation method from the smelt project. Note that this plugin is only for wind velocity on building with equal floors.

Wittig Sinha Equal Floors

This is the only RPS feature that the plugin implements. It belongs to the simulation method group. This feature implements the random wind velocity simulation method provided by the Smelt project which generate wind velocity time histories based on Wittig & Sinha (1975) model.

Properties

• DataGustSpeed: Gust speed of the wind.
• DataHeight: Building height.
• DataSeedNumber: Value to seed random variables to ensure repeatability.
• DataEventIndex: The index of the event whose time history should be shown.
• DataEventName: Name to assign to event.
